1k Injection Mold (Fan,Predeformation)

For PP products, deformation is the biggest problem. For this mold, the deformation problem is even more prominent. Because deformation can cause changes in fan resistance, resulting in excessive noise. When the length reaches about 300mm, it is not easy to control the deformation of the entire product surface. It becomes necessary to do Pre-deformation. Pre-deformation is not a simple addition or subtraction, because the deformation amount of plastic and the steel size of the mold are constant corresponding relationships.

Combined with 3D scanning measurement and repeated modifications to design drawings, our molds have met customer requirements. The customer was extremely satisfied.
